Did Plato abandon, or sharply modify, the Theory of Forms in later life? In the Phaedo, Symposium, and Republic it is generally agreed that Plato held that universals exist. But in Parmenides, he subjected that theory to criticism. If the criticism were valid, and Plato knew so, then the Parmenides marks a turning point in his thought. If, however, Plato became aware that there are radical differences in the logical behaviour of concepts, and the later dialogues are a record of his attempt to analyse those differences, then Plato’s thought can be said to have moved in a new and vitally important direction after the Parmenides. Studies in Plato’s Metaphysics brings together twenty essays by leading philosophers from the UK and the USA reflecting upon this important issue and upon the questions arising from it.

Studies of Plato’s metaphysics have tended to emphasise either the radical change between the early Theory of Forms and the late doctrines of the Timaeus and the Sophist, or to insist on a unity of approach that is unchanged throughout Plato’s career. The author lays out an alternative approach. Focussing on two metaphysical doctrines of central importance to Plato’s thought – the Theory of Forms and the doctrine of Being and Becoming – he suggests a continuous progress can be traced through Plato’s works. He presents his argument through an examination of the metaphysical sections of six of the dialogues: the Euthyphro, Phaedo, Republic, Parmenides, Timaeus, and Sophist.

This volume provides a comprehensive, learned and lively presentation of the whole range of Plato’s thought but with a particular emphasis upon how Plato developed his metaphysics with a view to supporting his deepest educational convictions. The author explores the relation of Plato’s metaphysics to the epistemological, ethical and political aspects of Plato’s theory of education and shows how Plato’s basic positions bear directly on the most fundamental questions faced by contemporary education.

This book offers a sympathetic explanation of the origin of the Theory of Forms that is true both to the dialogues and to Plato's place in history. The author's explanation makes the development of Plato's thought part of an intellectual and philosophical history that begins in the pre-Socratic period, extends through Socrates and the Sophists, and continues into the twentieth century. The explanation provides a unified reading of three passages that scholars have long recognized as keys to Plato's thought about the Forms, but which have proved stubbornly resistant to interpretation, both individually and as a group: (i) the intellectual autobiography in the Phaedo; (ii) the discussion of the philosopher and the lover of spectacles in the Republic; and (iii) the discussion of starting points, the Receptacle, and the four kinds of stuff in the Timaeus. The book will be of special interest to scholars of ancient philosophy, it will also be of interest to philosophers in general, graduate students, and advanced undergraduate students.
